the amount allowed walls of the hood, while the removable members 8, as their arcshaped faces 10 are preferably curved about a center, rearward of the coupler butt, will pivot about such center and slide along the curved faces 7 of the hood.

Under butting stresses the coupler shank moves rearwardlypwithin the hooded forward end of the yoke and compresses the shock absorbing mechanism. If the removable members 8 are provided with bosses 13 seating in the 'rivet holes 3 of the coupler liner block. they will travel rearwardly with the coupler shank. within the yoke hood. to the extent permitted by the shock absorbing mechanism.

In Figs. 8, t) and 10 modified form of the hood and removablemember. The hood 5 has at its forward end inwardly extending lugs 20 having areshaped bearings which engage the correspondingly shaped forward faces 21 of the removable members 8. Each removable member 8' has a face 22 arranged at right angles to the line of draft, against which the forward face of the liner block has a pulling bearing. Each removable member 8 has also a rearwardly extending portion free to move laterally y the flaring side 23 "\a'hi'ch very nearly fills the space between the top of the hood .5 and the liner block, or the bottom of the hood 5 and the liner block as the case may be. A forward extension 24 of the member 8 fits with the same clearance between the inner faces of the lugs 90 and. the shank of the coupler.

()ur invention is of particular advantage, since it provides for the piecemeal removal and replacement of the draft gear. coupler, yoke and various other parts. thus occasioning great saving of time and labor and making the device much easier to repair than the form-of rigging using the vertical yoke now in common use.

It is also to be seen that the hood at the forward end of the yoke greatly strengthens the yoke, and the use of the filler blocks for securing the coupler n the yoke forms a connection which makes the disengagement of the parts extremely easy and simple.

The terms and expressions which we have employed herein are used as terms of de scription and not of limitation. and we have no i (cation, in the use of such terms and expriesions, of excluding equivalents for the features shown and described, but recognize that various modifications are possible within the scope of the invention claimed.

hat we claim is: l. A coupler yoke having its arma urranged in a horizontal plane and hatrhg a hooded forward end adapted for reception of a couplerlincr block side, the hooded forward end of the yoke we have shown a tion, and a removable tion and any mechanical from the forward having webs joining the yoke arms and extending above and below the coupler liner block. and a securing member adapted to be inserted between the liner block and the yoke, said securing member being adapted to transmit draft strains from the coupler to the yoke.

2. A coupler yoke having the forward end arranged in a vertical plane in the form of an integral four-sided hood open at front and rear; and having a body portion arranged in a horizontal plane integral with the sides of the hood closed at the rear end and open above and below; adapted for the reception of a coupler liner block from the forward side and having horizontal pulling bearings arranged in planes parallel to the plane of the body por tion and above and below said body pormember adapted for insertion from the rear side of the hood between one of the pulling bearings of the hood and a forward face of the coupler liner block, and adapted to transmit draft strains from the coupler to the yoke:

25. A coupler yoke having the forward end arranged in a vertical plane in the form of an integral four-sided hood open at the front and rear and having a body portion arranged in a horizontal plane integral with the sides of the hood closed at the rear end and open above and below, the hood being adapted for the reception of a coupler liner block from the forward side, the hood having horizontal pulling bearings arranged in planes parallel to the plane of the body porabove and below said body portion, a removable member adapted for insertionfrom the rear side of the hood, between one of the pulling bearings of the hood and a forward face of the coupler liner block, and adapted to transmit draft strains from the coupler to the yoke, and shock absorbing mechanism set between the yoke arms and being removable vertically from below without disturbing the connection between the yoke and the coupler.

4. A coupler yoke having the forward end arranged in a vertical plane in the form of an integral four-sided hood open at front and rear and having a body portion arranged in a horizontal plane integral with the sides of the hood closed at the rear end and open above and below, the hood being adapted for the reception of a coupler liner block from the forward side. and a removable member adapted for insertion between the liner block and the hood, said member being adapted to engage a rear edge of the hood and to transmit pulling strains thereto from the coupler liner block.

5. A coupler yoke having the forward end arranged in a vertical plane in the form tbf an integral four-sided hood open atand rear and having a body portion arthe hood being f t, Ilbn 13 0 ranged in a horizontal plane integral with the sides of the hood closed at'the rear end and open above and below, the hood being adapted for the reception of a coupler liner block from the forward side, and a removable member engaging the coupler liner block and having an arc-shaped hearing intended to pull against an arc-shaped rear edge of the hood, said arc-shaped hearing being adapted to allow lateral angling between the coupler and yoke.

6. A coupler yoke having the forward end arranged in a vertical plane in the form of an integral four-sided hood open at front and rear andhaving body portion arranged in a horizontal plane integral With the sides of the hood closed at the rear end and open above and below, the hood being adapted for the reception of a coupler liner block.

froin the forward side, and a removable member adapted for insertion between the liner block and Hm hood from the rearward side of the hood, said member having at one end an upwa dly-extending lug engaging the rear ed e of the hood and at the other end a down wardly-extending lip engaging the forward face of the liner block. v

Y. A. coupler/yoke having its arms arranged in a 110i" o ntal plane, webs at the forward ends of the arms also arranged in horizontal planes and connecting the tops and bottomsqof said arms to form a boxlike structure open at both ends and adapted for the reception of a coupler liner block from its forward side, a removable member adapted in forflinsgartion between the liner block and the webs, said member engaging a rear edge of a, hood and being adapted to transmit pulling strains thereto from the 40- eonpler liner v block ERNEST H.
